GEORGE VILLIAM BROWN AND JOHN E. WILSON, OF DUB-YEA, PA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 338,135, dated March 16, 1886.

Application filed January 7, 1886.

To-aZZ whom it may concern:

Be it known that we, GEORGE WILLIAM BROWN and J OHN E. WILsoN, citizens of the United States, residing at Duryea, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Improvement in Draw-Bars and Couplings, of which the fol lowing is a specification, reference being had to the accompanying drawings.

Our invention relates to improvements in draw-bars and couplings for cars used in coalmines and the like; and the novelty consists of the peculiar construction and combination of parts substantially as hereinafter fully set forth,and specifically pointed out in the claims.-

The object of our invention is to provide an improved device of the class named which is especially adapted for use upon cars that are employed to convey coal in or about a coalmine or thelike,which device can be operated very quickly and easily without requiring the attendant to pass between the cars, so that the car can be readily disconnected from the winding-drum and rope of an engine when it reaches the end of an incline'without danger to the attendant; and a further object of our invention is to provide our device with improved means whereby the strain on the pivots will be reduced to a minimum; and the device is simple, strong, and durable in construction, and comparatively cheap and inexpensive of manufacture.

Referring to the drawings, Figure l is a view showing our improved draft-bar and hook connected to the rope of a winding-drum and a car. Fig. 2 is a detail perspective view of the draft-bar and hook detached. Fig. 3 is a longitudinal vertical sectional view through Fig. 2 on the line 00 00 thereof, showingthe position of the parts in dotted lines after disengagement with the car.

Like letters of reference indicate corresponding parts in all the figures of the drawings, referring to which A designates our improved draw bar and hook. B designates the drawingrope of a winding-drum,which is actuated by an engine, and G a car for conveying coal from a mine to a place of deposit.

The draw-bar'A has a projecting lug or Serial No. 187,859. (No model.)

shoulder, a, at one end, and to this lug a is connected a draft-eye, D, by means of a pivot pin or bolt, I), that passes through the lug a and enlarged ends or heads I) of the draft-eye, the lugs I) fitting 011 opposite sides of the lug a and have the pivot pin 1) secured therein. The rope, chain, cable, or other flexible con nection, B, of the winding-drum is connected to the pivoted eye D, and the opposite end of the draw-bar A is connected to the car 0 by a link, E, and a pivot pin or bolt or other suitable connection.

The draw-bar A has two upwardly-project ing lugs, f, at end thereof that is adjacent the car O, and which, for the sake of convenience, we will term the rear end; and the drawbar is further provided with a transverse groove or recess, f, in its upper face, and at a short distance in front of the lugsf.

G designates a clasp or hook, which has a curved centrally-located tongue, 9, at one end, which is arranged between and pivoted to the lugs f of the draw bar, the rear end of the clasp being cut away on each side of its pivottongue 9 to bear on the inner faces of the lugs f. This clasp G is adapted to be moved to a horizontal or vertical position on its pivot, and it is provided on its under face with a transverse groove, 9, that is adapted to register with the groove f of the draw-bar A when the clasp lies in its horizontal position. The ends of the grooves f gare recessed, as shown, and when the grooves register they provide a socket for the reception and retention of one of the cross-bars of the link E. At its front end the pivoted clasp has a lug or stud, h, provided with a transverse opening, h, and over this lug fits a locking device, I, which comprises a bow shaped piece having its lower ends fitted on opposite side faces of the drawbar and pivoted thereto, so as to move oroscillate back and forth to engage and release the lug of the pivoted clasp. The locking-bow I has a thumb-piece, t, for its convenient operation, and at one side it has a set-screw, i, that is adapted to clamp the device rigidly in position.

A pin, J, is passed through the opening h of the pivoted clasp, and this pin is secured by a chain, L, &c., to an eye of the pivoted loop to prevent it from becoming detached and lost and to adapt the device for simultaneous operation.

The operation is as follows: The draft-eye D is connected with the rope B of the winding-druln or a car ahead of the said draft'eye, and the link E of the succeeding car is secured in the groovesf g by the pivoted loop I locking the clasp G in position, the pin J being inserted in the recess or opening 71/ of the linkclasp G, and the cord L extended to a point outside of the car and suitably held in position. When the car 0 reaches the point where it is desired it shall remain or discharge its load, the attendant or operator withdraws the pin J by pulling on the cord L, and the pin being connected to the pivoted loop I a continued pull on the cord draws the loop from engagement with the pivoted clasp. When the loop is disengaged from the pivoted clasp, the continued strain or draft on the link E will serve to turn the pivoted clasp rearwardly, and thus allow the link to be freed. By means of the recesses in the clasp on opposite sides of the pivot lug 9 thereof, and which recesses bear on the upwardly-projecting lugsf, the strain exerted by the link E on the clasp and rear end of the draw-bar is taken up by said lugs f and away from the pivot pin or bolt between the bar A and clasp G.

To connect a link, E, with the draw-bar and clasp, the pivoted clasp is thrown back and one of the cross-bars of the link fitted in the groove f, after which the clasp is turned down to secure the link between its groove and that of the draw-bar, the pivoted loop and transverse pin being adjusted as before described.

The thumb-screw is allowed to remain loose when the device is in use, but when it is detached from a car the said screw is tightened up to hold all the parts rigidly in place.

Having thus described our invention, what we claim as new is l. The combination of a recessed draw-bar, a link-retaining clasp pivoted thereto at one end and having a recess that registers with the recess thereof, a locking loop pivoted to the draw-bar and engaging the free end of the clasp, a transverse pin, J, passing through the free end of the clasp and bearing against the loop, a rope, L, connected to the pin, and a rope, L, connected with the rope L and the pivoted loop, substantially as described.

2. Thecornbination, in adraw-bar and coupling of the class described, of a bar, A, having a draft-eye, D, the transverse groove f, and the lugs f, a clasp, G, having a lug, g, pivoted between and to the lu gs f, and having a groove, 9, a loop, I, pivoted to the bar A and adapted to confine the free end of the clasp G, a trans verse pin, J, passing through the lug in front of the pivoted loop, a cord, L, connected to the pin, and a cord, L, connected to the cord L and the pivoted loop, substantially as described.

In testimony that we claim the foregoing as our own we have hereto aflixed our signatures in presence of two witnesses.
